' PRINTING-MACHINE.

To all whom it may concern:

Be it known that I, ALBERT B. DICK, a

citizen of'the United States, residing at Lake Forest, in the county ofLake and State of Illinois, have invented a certain newand usefulImprovement in Printing-Machines, of which the followingis aspecification.

This iny ention relates generally to printing mechanism for roducingmultiple copies,

and although not limited thereto is designed more particularly for thatty e of printing mechanism in which is emp oyed a typeform, the ty gleplane ant such form being supported in a suitable carriage which is rjciprocated, as

the paper is fed, to bring the came into coaction with the face of saidform.

The object of the invention, broadly stated, is to produce a simple,durable and highly efficient apparatus of this general character.

In carrying out the invention, I employ a suitable stationary frame,upon which operate a carriage supporting the type-form, and

in addition an inking device, of which an inked ribbon is a convenientform. Supported in the frame, is a pressure-roller,

movable to operative and inoperative ositions, and, intermediate of saidroller ant the reciprocating carriage I employ mechanism, preferablycontrolled by the operation pf the atter,.f'or moving saidpressure-roller to op-' printed upon.

A preferred form of the invention is illustrated in the drawings, inwhich Figure 1 is a side elevation; Fig. 2 is a cen-' 'tral longitudinalsection; Fig. 3 is a plan 0 view; Fig. 4 is .a cross-section onthe line4+4 Fig. 1, .certain parts being omitted for clearness; and Fig. 5 is adetail view, hereinafter to be referred to.--

Referring to these drawings, A designates a suitable base, upon whichthe machine Specificationof Letters Patent.

may be secured. The frame of such machine comprises the side members B,B, and these may be connected, if desired, by cross-bars 6,1), 6 b andb. Coacting withthe side members B, B, is the carriage which supportsthe type-form and ink-ribbon, and which carriage includes the sidemembers C, C, provided with downwardly and out wardly turned ribs 0, c,which coact with grooves or rabbets c 0 formed on the inte-r- 13 nalfaces of the side members B, B, of the frame, near their upper edges.

c designatesv an inwardly extending bracket secured to or formedintegral with the member C of the carriage, and to this is secured adepending plate 0 provided with an elongated slot 0 That portion clofthe plate c bounding the lower extremity of the slot 1: serves as adriving rack or other surface forthe sheave cl presently to bedescribed, I the same being preferably milled or otherwise roughened forcoaction with said sheave, the surface of the latter being referably ofan elastic material such as rub er.

E designates a feed-board, here shown as mounted upon studs e carried bythe crossbars b b and preferably faced with rubber at e at its outer endand with a smooth and non-elastic material 6 forward of such 'rubberfacing. The extreme forward end of the feed-board is preferably providedwith a slightly upturned lip e for coaction with the impression-sheet eSaid feed-board may be provided with adjustable side-guides e havinginturned forward edges e.

F designates a bracket arranged close to the internal face of the sidemember B of the frame and havin 'a 'ournal bearing f operating in-avertical lane within a suitablyshaped slot f in sai' member.F-designates a generally similar bracket arranged ad acent to theinternal face; of the side member B of theframe and having a 'ournalbearing f operatin in a vertical plane in a suitably shaped slot f 3 insaid member. Each of said brackets is here shown as rovided with an earf to which is connected one end of a coilsprmgf the other end'whereof issecured to t e base A so as to exert downward pressure upon saidbrackets and journal bearin s.

v D designates the lower feed-rolh'the shaft d whereof is mounted in thejournal bearing f, f, and extends through the same, projectin beyond themachine on either side. Said r0 l is provided with a suitable clutch dwhereby the same may be positively driven,

as hereinafter described, for the feeding oper- 'ation, but free aftersuch positive driving to be rotated by the continued movement of theimpression-sheet. The sheave d is secured upon the shaft of said lowerfeed-roll D, its

periphery coa'cting', as above stated, with the milled surface cof thede endin plate 0 Saidshaft alse carries apo ygona wheel d, the peripherywhereof coacts with a'cam d 'adjustabl secured, as by means of set-screwd, to tlfemterna'l face of the, depending plate the forward end of saidcam being beveled,

as shown at d. As, therefore, the carriage is moved toward the left(Fig. 2), the sheave d, coactingwith the milled surface a, is ositive'lydrivenfthereby until the beveled end (if ofthe cam d comes contact withthe polygonal wheel d when said wheel, riding on said cam (1 raises thesheave at out of contact with said milled surface 0', thereb bringingsaid sheave and the shaft on whic it is mounted to rest except to suchextent as said shaft may thereafter be rotated by the pull of the sheetwhich has been fed over the same. Said lower feed-rollD or its shaft-dis here, shown as provided with a pinion (1 which meshes with a similargear 9 on the shaft 9" of up er feed-roll G, which may be sectional (ass own) or continuous from end to end. The roll 1) is referably of metalor metal cOvered, while t e roll G is preferably of rubber orrubber-covered. The shaft g is journaled in cars 9 preferably formed integral with the brackets F, F4. rigidity, I prefer to connect thebrackets F, F by means of cross-bar F below which the im ression-sheet emay pass after it has been fe between the rollsD and G.

H designates the pressure-roller, the shaft h of which projects throughvertical slots in the side members B, B, of the frame.

One end of said shaft h is journaledn a suitable bearing in the arm hhinged at 72, 'to the side member B, the other end of said shaft beingjournaled in a suitable bearing in the arm h hi ed at h to the sidemember B One or bot of said hin ed arms h, h may be provided with abuffer h Each of said arms is provided witha toe h directly underlyingthe extremities of the shaft (1 of the lower feed-roll D, the purposewhereof will presently be explained.

Underlying the shaft h of the pressureroller H, is another shaft 1,journaled at its ends in fixed bearings in the side members B, B, of theframe and projecting therethrough. Outside the side member B of theframe, there is keyed to said shaft I a cam '11, and in addition acam-lever i, which may also, if desired, be secured to the cam I, as byscrews Outside the side member B of the frame,

said shaft I is also provided with a cam i (see Fig. 5) Both these camsi and i coact with the hinged arms h. if. in the manner For greater.

indicated in Figs. 1 and 5 As the can 1,1111 1', is thrown toward theleft (Fig. 1), the cams '21, t operate to raise the hinged arms h, h,

and therefore. the pressure-roller H carried thereby. And through theengagement of the toes h withthe ends of the shaft 11 the lower'andupper feed-rolls D, G, and their brackets and other mechanism are"correspondingly elevated. This throwing of the cam arm i. andconsequent elevation of the several parts referred to is effected bymeans of a stop iborne by the type-carriage. Said type-carriage is alsoprovided with another stop 'ifi'at its opposite end, which also coactswith said cam-arm i. It will thus be seen that as the carriage is movedtoward the right, Fig. 1, the coaction of the parts i and i causes thedepression of both the feed dey vice and the pressure-roller, while themovement of the carriage-toward the-left, Fig. 1,

and the consequent coaction of the parts i and i causes the elevationofsaid pressureroller and feed devlce, as above indicated;

I prefer that the shaft h of pressure-roller H be positively driven, andalso that the movement of the same" commence prior to the moment ofcoaction of'thc type-form (presently described) therewith, inorder thatsuch movement may be under way at the I time it is actually utilized. I,therefore, provide said shaft h, outside the side member B andbetweenthe same and the hinged arm 72?, with a sheave h, the periphery whereofengages with a rib h supported upon the 'side' member C of the carnage.As the carriage is moved toward the left, Fig. 1, and

as the coaction of the stop 5; with'the camarm 1'. raise-s thepressure-roller H to operative position, the sheave k (which may be ofrubber or rubber-covered) ,is brought into coaction with said rib h, sothat from the start of the returnmovement of the carriage (towardthe'right) this coaction will result in ink-ribbon J, the ends whereoare mounted upon spools J, J the former carried b brackets and thelatterby. brackets j. Eac of said spools is connected; referablydetachably, with a'pim'on K, K fand coacting with each of said inions isan operating sector 7:, 7c, and the ower ends of these sectors are hereshown as coacting with cams 7c carried by the side members B,Brespectively of the main frame.

As the spools and eir operating mechanism forms no part of the presentinvention, it will suffice to say in general that, the ribbon is wounduponone and fed therefrom to the other, this being accomplished by theco.

action of one of the sectors 70 with oneof the cams 7r at the limit offorward or reverse movement of the carria e. Said spools may be providedwith suita le clutches, so that either may be driven to'take up theribbon while the other is loose so as to permit the ribbon to be sotaken up. With t ese spools may be combined an automatic reversingmechanism, so that when after moving in one direction,- the end 'of theribbon is reached, the return movement of the ribbon in the, op ositedirection may be effected without a ditionalmanipulation. S'aidribbon ishere shown as running from spool J "over idler-rolls-lfi, k past thetlype faces,

Such type on being E into the channels may be brou ht to astop'by means of such shoulders, eaving their printing faces insubstantial aline- -mentl- It is preferred that said type be 1 surfaceof the plate 0 a sheet or sheets or block of other material, 0 such, forinstance, as paper.

the carriage in any suitable manner. In the drawings, a convenient meansis shown, comprising the ears P, P, secured tothe carriage and belowwhich one end m of the typec'arrying frame may be placed, the other endbeing secured inosition by means of setscrews P, P (see igs. 2 and 3);

The ap aratus may be rovided with any suitable f drm of deliverycard ortray designed to receive the imprinted sheets. I have shown in thedrawings a portion of a delivery-board Q, one end whereof is carried bythe cross-bar b, said board resting upon and being secured in anysuitable manner to the cross-bar b, in order to receive the sheets afterthey have been printed and fed beyond the ressure-roller H.

T 1e operation of the apparatus has been to some extent indicated in theforegoing description, and need therefore only be sum marized. In orderto prepare the apparatus for the printing operation, the type are setup, the pad n and pressure-plate O adjusted, and the latter secured, andthe type-holding frame locked in the carriage. The sheets are fedforward over the feed-board E successively, a sheet being passed to thebight of the feed-rolls D and G when the carriage is at the end of itsexcursion toward the right, Fig. 1. At this time, the coaction of thestop 11 and cam-arm 'i has resulted in depressing both theressure-roller and the feed-rolls, as above in icated. The sheave d ofthe feedroll D is, therefore, in coaction with the milled surface 0 atthe edge of the slot 0 Therefore, as the carriage is moved toward theleft, said feed-rolls are operated in 0 p0- site directions to seize theforward end 0 the sheet and to pass the same rearwardly and over thereferably hard) surface of the ressure-ro ler H. This action takes placeso ong as the feed-rolls are operated, which is until the coaction ofthe olygonal Wheel (Z with the cam (Z breaks t e engagement between saidsheave d and milled surface 0 The continued movement of the carriagetoward the left brings the stop i into contact with the cam-arm 71,moving the same to the position shown in Fig. 1. This raises thepressure-roller as well as the feed-rolls D, G, the former, however, toa higher lane than the latter, the periphery of sai pressureroller beingin close juxtaposition to' the ribbon J, which in turn is eitherincontact or almost in cont ct with the type faces. The moment theforward movement (toward the right, Fig. 1) commences, the engagement.of the sheave h with the rib it sets the pressureroller in operation,and when therefore the first tfype of the type-form reach said rollerthey 1nd the same moving at substantially the same surface speed. This"feature is deemed to be of im ortance, as the feed-rolls D and G havingfed the impression-sheet for- ,ward over the pressure-roller and thesame havingbeen brought to rest, the sheet is, in effect, grippedbetween the type-form and the pressure-roller (the ribbon J beingstationary relative to the type-form) and the further movement'of theimpression-sheet depends entirely upon this coaction. As, therefore, thecarriage and type-form are further moved toward the right, thecharacters of the type faces are imprinted upon the sheet, through theribbon, and the sheet passed on with the carriage until free from thecoaction thereof with said pressure-roller, when it falls upon thedelivery-tray Q. As this occurs, the coaction of the stop with thecam-arm '5 again depresses the pressure-'- roller and the feed-rolls,whereupon another sheet may be assed to the latter and the operationjust escribed repeated.

The im ression received by the sheet is evenly printed and all thecharacters are sharply defined. This resultsto a large ex tent fromcertain features of the arrange ment of the cooperating parts of theprinter as shown herein and which are considered of -great importance. Ihave found that much superior results are obtained by so supporting thety e upon the'carria'ge that the lines thereo extend in the ,directionof movement of the carriage and by mountingthe pressureroller so thatitextends across the lines of the t pe, preferably with its axistransverse to t e lines of type. I This arrangement of the parts withtype that are loosely mounted so as to yield somewhat, gives a uniformand reliable coaction of the type and pressureroller with the sheet over.the entire impression and results'in sharp definition andeven printingof all of the characters. If the lines of type extended across themachine at a right angle to the direction of movement, the printingmovement of the carriage would bring practically a continuous edge oftype into engagement with the ink-ribbon and sheet along the line ofcontact with the pressure-roller, and as a consequence, the forward edgeof the characters at that edge of the sheet-1 which was first rintedmight be somewhat blurred; and if t e several lines of type wereseparated by considerable space, the forward edge of the succeedinglines of type might also be blurred and slight blurring might occur attheir rearward edges. W'hen the type are arranged in linesextendinginthe direction of movementof thecarriage, the ty e firstengaging theressureroller througi the sheet and ink-ri bon are those at the end ofthe lines which, instead of forming a solid edge of type are spaced aart byfthe distance between the lines. T'ese move longitudinallybackward the slight amount permitted by the'backing, and press 3 agr 1stthe roller with the required pressure.

and the following type in the several lines hold all the parts int-hesame relation so that there is no jarring or other movement such aswould cause blurring and uneven printing.

Blurringof that portionof the sheet which is first printed is furtheravoided by the provision of mechanism for starting the rotation of thepressure-roller before the printing of V the sheet is actually begunsince this preventsthe slight amount of slip .and consequent blurrin ofthe impression which would take place the rotation of thepressure-roller were started by the engagement of the type 1 therewiththroughthe ink ribbon and sheet,

particularly when the carriage is rapidly operated. For the samepurpose, I consider it important .to have the pressure-rollersupportedpositively in its operative or elevated position so that there will beno movement thereof during the printing operation. This is effected bythe cams i which support the pivoted arms h carrying the pressureroller. 35 Having now described -m invention, what I claim as newthe-rein and esire to secure by Letters Patent is as follows z- 1.
